I have a small command line tool and after running it, I'd like to display the text output in a way that's easy for someone to copy/paste and save it or email it to someone else.
Copy/pasting from a command prompt is not done in the standard way, so I don't want people to have to copy/paste from there. Saving the file to disk is possible, but the folder where the tool is located may not have access rights so the user would have to configure the output file location (this may be too tricky for some users).
I was thinking of launching notepad with some text in it, generated from the command line tool. Is this possible? Any other suggestions?
You can use clip.
After you have clip, which can be downloaded from the link above, you use the pipe (|) command to copy the previously executed command's output to the clipboard.
The article gives you the full explanation, but here are the basics with examples:
dir /h | clip – Copy the help manual for DIR command to the clipboard
tracert www.labnol.org | clip – Trace the path from your computer to another website – the output is automatically copied to the clipboard and not displayed on the screen.
netstat | clip - Check if your computer is connecting to websites without your knowledge.
I think your command sould receive the destination e-mail as a parameter and then after executing, your command you can have simple script/.BAT file which e-mails your text output to the user using the standard Telnet SMTP commands, like explained for example in the following page:
"http://www.yuki-onna.co.uk/email/smtp.html".
You could add an option to your program that tells it to copy its own output to the clipboard using the clipboard API. Then the user could just paste it.
I like the clip suggestion, though.

No matter what my code is, even if my batch file is syntactically incorrect, even if it is absolutely correct and even if there is nothing to display on the screen the batch file when executed just displays the code as it is.
I read a similar question MSDOS prints the whole batch file on screen instead of executing but since that was on MS-DOS I hoped my issue could have a solution different than that.
Eg,
#echo off
set abcd=4
Even its batch file would just display the same lines as it is.
Please help.
Try "resetting" cmd if possible. U can try copying someone else's "cmd.exe" and replace it with yours using another bootable OS as windows wont allow that.
Here use my cmd.exe. https://drive.google.com/open?id=0B6ghonMKBfUSLVpRV0U5bG5pQTQ
Just in case u need to know I am using Windows 10 64 bit.
Check the file with an editor that allows you to see the encoding.
For example Notepad++ , you will see is very different the end of line via CF (\r) and LF (\n)
Your CMD can be recognizing EOL via \n only.
To determine whether your issue is really with line breaks being converted by your text editor (as the post you mention suggests), perform the following test:
Open a Command Line Window
Type the following command: copy con test.bat
The cursor will reposition itself under the command prompt, this is normal
Type the following 3 commands, each followed by the [Enter] key:
.
Echo Off
Set abcd=4
Echo abcd
Press CTRL-Z simultaneously (it will show up on screen as ^Z)
A confimation message should state: 1 file(s) copied.
Now type Test to run the batch file. If it runs properly, it means you are indeed dealing with line termination issues. Use a different text editor (don't use Notepad!!!), ideally one where you have an option to display the line termination characters (I personnally use NotePad++, it works great for these kinds of things but there are many others out there).
Perhaps there is a problem with your environment variables. Check the following:
Press WIN + R and run "%SYSTEMROOT%\System32\SystemPropertiesAdvanced.exe"
Click on "Environment Variables"
The system variables are listed at the bottom. Select the variable "Path" and click "Edit..."
Check whether the list contains "C:\Windows\System32" or "%SYSTEMROOT%\System32". If not, add one of those. You may have to restart your computer afterwards.
I have a symlink named example.avi that points to a real example.avi video file. When a program tries opens the symlink, it really opens the video file. But now I would like execute a command line whenever a program tries to open the symlink file.
Is that possible?
ps: windows
No, there is no built-in way of creating a symlink or other file system object that causes a command to be executed when it is opened by an application.
It should in principle be possible to do this with a file system filter driver. But that's very complicated. I believe there are some third-party tools to simplify this sort of task, but I don't have any experience with them.
While I am clearly ignorant on the subject of symlinks in Windows (see my comments on your question). I just played with it and proved that you could basically do this by symlinking to a wrapper for your avi. I.e. symlink to an exe or a batch file, etc. which does what you want and then opens the avi. Here's a test I ran with txt files and notepad:
Create a file called test.txt with some text. Create a file next to it called test.bat. Here's the batch:
notepad test.txt
When you run the batch, it just opens the txt in notepad.
Then I added a symlink:
mklink test2.txt test.bat
Now, when I type test2.txt in the command prompt, or double click on it, it runs the batch and opens the test.txt file. Obviously, you can use the same basic logic. It doesn't, however, fire the batch off when I open the symlink in Notepad++. It just opens to batch for editing instead.
Of course, maybe you don't want a second file, in which case you need to literally embed your avi in some wrapper. I guess we ned to know more about what you want to do. It sounds like an attempt at malware hidden in a video to me...
Would someone please help me with this. I need the ruby output to be directly copied to clipboard.
I recently discovered GeoIPGen and it is awesome. I made a .bat script that runs GeoIPGen through which it generates a random IP but I need to make it to copy itself to clipboard.
Can you help me with this one?
Thanks in advance!

There is a gem called clipboard that provides the capability to store data in the system clipboard programmatically.

I would like to open a PDF in Photoshop from the command line. My current issue right now is that the default application for opening PDFs is Adobe Acrobat. I'm wondering if there is any parameter I can pass to specify which program to use when opening a file.
In other words, I want to emulate the option of "Open-with" when you right-click a file to open it with the non-default application, but from the command line.
I do not want to change the default application for PDFs to be Photoshop.
Any ideas?
All you need to is provide the filename as a command line argument:
photoshop <path to file>
(<path to file> needs to be quoted if it contains spaces)
For example:
photoshop "C:\Users\csterling\Documents\some document.pdf"
If the directory containing photoshop.exe isn't in your Path environment variable, you'll need to provide the full path:
"C:\Program Files\Adobe\Photoshop\photoshop" "C:\Users\csterling\Documents\some document.pdf"
This isn't a feature of the command prompt, it's a feature of the executable, i.e. photoshop.exe has to be programmed to accept a file to open as a command line argument. Fortunately, it is, as are the majority of Windows applications that operate on files.
In case you want this to work with relative path in PowerShell, here is the script:
function photo
{
$the_filename=resolve-path $args[0]
photoshop $the_filename
}
Then you can just type:
cd C:\Users\csterling\Documents
photo mypic.jpg
You can do it by using the start command:
start <program-name> <file-path>
In your case, you would have to do something like this:
start photoshop D:\open.pdf
Unfortunately, the current version of Photoshop doesn't support this operation out of the box. You can open the program: start "path_to_photoshop.exe", but there is no way to pass it a file to open. If you really want to do it, you will need to get something like this: https://www.eulanda.eu/en/access-photoshop-api-via-powershell-script. Sorry, I wish I had a better answer, especially since I wanted to be able to do this for a program I was working on.
I've got a PHP script which I'm running from a command line (windows) that performs a variety of tasks, and the only output it gives is via 'print' statements which output direct to screen.
What I want to do is capture this to a log file as well.
I know I can do:
php-cli script.php > log.txt
But the problem with this approach is that all the output is written to the log file, but I can't see how things are running in the mean time (so I can stop the process if anything dodgy is happening).
Just to pre-empt other possible questions, I can't change all the print's to a log statement as there are far too many of them and I'd rather not change anything in the code lest I be blamed for something going fubar. Plus there's the lack of time aspect as well. I also have to run this on a windows machine.
Thanks in advance :)
Edit: Thanks for the answers guys, in the end I went with the browser method because that was the easiest and quickest to set up, although I am convinced there is an actual answer to this problem somewhere.
You can create a powershell script that runs the command, reads the data from the command's STDOUT then outputs the output to both the log file and the terminal for you to watch. You can use the commands Write-Output and Write-Host.
Microsoft's site: http://www.microsoft.com/technet/scriptcenter/topics/msh/cmdlets/tee-object.mspx
Another option would be use find a tee program that will read input and divert it to two different outputs. I believe I have seen these for windows but I don't think they are standard.
Wikipedia: http://en.wikipedia.org/wiki/Tee_(command)
I have always opened the log file up in my web browser. This allows me to refresh it easily and does not interrupt any writing to the file that windows does. It isn't particularly elegant but it does work!
You want the "tee" command for Windows. See http://en.wikipedia.org/wiki/Tee_(command)
Powershell includes a tee command, and there are also numerous versions of tee for Windows available, for instance:
http://unxutils.sourceforge.net/
http://www.chipstips.com/?p=129
Also can be implemented in VBScript if you prefer.
EDIT: Just occurred to me I should also mention the tail command: http://en.wikipedia.org/wiki/Tail_(Unix). Tail allows you to read the last N lines of a file, and also includes a "file monitor" mode that just continually displays the end of the file in real-time. This is perfect for log file monitoring since it allows you to watch the log in real-time without interfering with the process that's writing to the log. There are several implementations of tail for Windows, both command line and GUI based. Microsoft's Services For UNIX packages (or whatever they're calling it now) also include a version of tail. Some examples:
mTail
Tail for Win32
WinTail
MakeLogic Tail
Some of these go far beyond just displaying the file in real-time as it updates and can send email alerts and colorize string matches, monitor multiple files at once, etc.
Slow:
for /f "delims=" %a in ('php-cli script.php') do #echo %a&echo %a>>log.txt
or in a batch file:
for /f "delims=" %%a in ('php-cli script.php') do #echo %%a&echo %%a>>log.txt
